This way it can determine the type of service being provided. Please be aware here, that when we are talking about "ports" we are not talking about ports that are used for serial and parallel devices, or ports used for computer hardware control. This means there are four numbers, each separated by a dot. Each number represents a one byte value with a possible mathematical range of 0-255. Briefly, the first one or two bytes, depending on the class of network, generally will indicate the number of the network, the third byte indicates the number of the subnet, and.
This numbering scheme will vary depending on the network and the numbering method used such as Classless Inter-Domain Routing (CIDR ) which is described later. The host number cannot be

This numbering scheme will vary depending on the network and the numbering method used such as Classless Inter-Domain Routing (CIDR ) which is described later. The host number cannot be These ports are merely reference numbers used to define a service. For instance, port 23 is used for telnet services, and HTTP uses port 80 for providing web browsing service. There is a group called the IANA (Internet Assigned Numbers Authority) that controls the assigning of ports for specific services. This can be done automatically using network software such as dynamic host configuration protocol (DHCP ) or by manually entering static addresses into the computer. Ports The TCP layer requires what is called a port number to be assigned to each message. If not listed, the service/protocol can use both TCP and UDP. Table C-1 lists the Well Known Ports as defined by. IANA and is used by Red Hat Enterprise Linux as default communication ports for various services, including FTP, SSH, and Samba. Red Hat Enterprise Linux 4: Security Guide. Prev Next The following tables list the most common communication ports used by services, daemons, and programs included in Red Hat Enterprise Linux. This listing can also be found in the /etc/services file. Addresses Addresses are used to locate computers. It works almost like a house address.

There are other alternative mechanisms for managing network traffic, but most, such as IPX/SPX for Netware, will not be described here in much detail. The IP layer requires a 4 (IPv4) or 6 (IPv6) byte address to be assigned to each network interface card on each computer.
Without an IP numbering system, it would not be possible to determine where network data packets should go. IPv4, which means internet protocol version 4, is described here. Each IP address is denoted by what is called dotted decimal notation.
